On a somewhat relevant but not really relevant case, I am running the 7850 @ max settings with 1920x1080 with beta 2 driver.

My question is, when I use the mouse to turn while strafing (both mouse buttons held down, moving mouse left and right while pressing a/d to strafe), the graphics like stutter almost. It isn't too bad or anything it just makes the distant images shake a little bit. Do you guys think this is:

1) internet issue/ping/latency
2) mouse sensitivity issue (I use the razor abyssus - it's fairly sensitive from playing SC2)
or 3) GPU/System issues?

I ran the benchmark with a score of 7450 on max full screen 1920x1080, so I don't think it's the latter. Any tips would be appreciated!
